Hello, On Wed, 29 Mar 2017 14:44:29 +0200, Antoine Tenart wrote: > + cpm_crypto: crypto@800000 { > + compatible = "inside-secure,safexcel-eip197"; > + reg = <0x800000 0x200000>; > + interrupts = <GIC_SPI 34 (IRQ_TYPE_EDGE_RISING | IRQ_TYPE_LEVEL_HIGH)>, Now that I look into this, does it makes sense for an interrupt to be both an edge interrupt and a level interrupt at the same time? This looks odd. Best regards, Thomas

This > looks odd. I agree this looks odd. I took it from Russel's ICU mapping: http://lists.infradead.org/pipermail/linux-arm-kernel/2017-February/489040.html Also note the driver does not use it (yet?). Antoine
